Main features of Coriolis mass flowmeter

Coriolis mass flowmeters are leading precise flow and density measurement solutions, providing the most accurate and repeatable mass measurement for liquids or slurries. The U Series Coriolis mass flowmeter is an advanced, high-precision mass flow measuring instrument featuring flexible configuration, powerful functionality, and a high cost-performance ratio. It is a commonly used structure among the new generation of mass flowmeters. It has low requirements on fluid conditions and can exhibit excellent performance even in harsh working environments.

Application Fields

The characteristics of the mass flowmeter determine its wide application in the following fields:

Metering of fluid energy, fluid raw materials, and products – e.g., metering of petroleum, chemical raw materials and products during loading (onto trucks/ships) and unloading (from trucks/ships), as well as packaging metering.
Precise metering and control of materials in production processes of the petroleum, chemical, food, and pharmaceutical industries.
Online metering of high‑viscosity materials – e.g., asphalt, heavy oil, and grease.
Metering of materials containing suspended solids and solid particles – e.g., cement slurry and lime slurry.
Insulated metering of easily solidifiable materials – e.g., asphalt, allowing metering while maintaining a heated state.
Accurate metering of medium‑ and high‑pressure gases – e.g., CNG (compressed natural gas) and petroleum natural gas.
Micro‑flow measurement – e.g., in fine chemical and pharmaceutical industries.
Online measurement of medium density, and thereby deriving the concentration of solutes in a solution – e.g., measuring lime concentration in lime slurry.
Measurement of cryogenic media – e.g., liquid nitrogen, liquid oxygen, and other liquefied gases.
Flow measurement of high‑temperature media – e.g., high‑temperature oil (up to 200–300°C).
Flow measurement of high‑pressure media – e.g., cement slurry flow in oil well cementing (up to several tens of MPa), etc.
